I was at a bar a while ago and they showed this movie where it looked like a bunch of people trapped in a warehouse and everywhere they went there was graffiti on the walls that had band names on them like Pink Floyd and Metallica on it.The villain looked like a zombie with some flesh missing. There was one scene where a girl with a pipe was fighting zombies or some monsters with a pipe and she was thrown into a machine and was crushed into a cube. I really want to know what film this is and have looked on online and couldn't find anything.
